Introduction and Theory:
- A potentiometer is a variable resistor consists usually of a turning dial to change the value of its resistance between two of its terminals.
- The resistance between the wiper (b) and either side of the outer terminals (a or c) varies from zero to a maximum of the full rating of the POT.
Rmax = Rac = Rab + Rbc
- A Wheatstone bridge is a circuit used to measure the resistance of an unknown resistor.
